ROCKET JET HEAT — A 1957 space card from Topps. From the reverse side: “The glaring white hot jets melt the rocks below producing a small man made moon volcano. Rocks bubble and run off through crags and crevices. Finally the spidery steel legs of the space ship touch down! Reports are flashed back to the control center on earth and the news goes all over the world. Man has landed on the moon!”
